Which of the following does not require preheating during storage in the storage tank as well as during atomisation through burners ?
Correct answer: C. Light diesel oil
- A. PCM
- B. Tar
- C. Light diesel oil
- D. Low viscosity furnace oil
Explanation
Light diesel oil has sufficiently low viscosity to flow and atomise without preheating. Tar, PCM and furnace oils are more viscous and need heating for storage or burner atomisation.
